Title: Power mosfet manufacturing method
Inventor: KAWAMOTO ATSUNOBU
IPC: H01L29/78
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce the defective occurrence ratio due to shorting between the gate and source electrodes by avoiding placing the gate electrode in a lower part of a bonding wire joint and ultrasonically bonding the wire at specified frequency. SOLUTION: In application to a vertical power MOSFET, a p-type well region 12 is formed in an n-type layer 4 formed on a semiconductor substrate 1 so that a lower region of a source pad 3 is a p-type region, resist mask is formed to cover the region 12, and n<+> -layer 7 to be a source region is formed in the p-type well wherein the p-type region of the pad region 3 is covered with the resist mask during this process to avoid forming a gate electrode cell in a lower part of the pad region 3. Even if the wire bonding to the source pad region 3 is made at a frequency of 50-70kHz, shorting never occurs between the gate electrode 8 and source electrode 9.

Filed: 1980-02-05
Abstract: PURPOSE: To perform stable operation of recutting throughout the whole circumference and improve accuracy of remachining finish in wire-cut work where a wire electrode of thin wire is utilized to perform cutting work into a required shape, by increasing depth of cut at recut machining.  
     CONSTITUTION: After wire-cut coarse machining work is performed, required depth of cut is given to between a wire electrode 1 and work body 6 to perform remachining operation for a coarsely machined face. Depth of cut l at this time is given by increasing a machining enlargement margin α at coarse machining (n) times of a value in proportion to plate thickness of the work body 6, that is, to obtain l=nα. A shape feed given to the work body 6 by an NC controller 10 at this remachining is performed in such cut as shown by a dotted line with an enlarging feed where the depth of cut l is added to a shape feed of the initial machining. In this way, the specific depth of cut l at remachining can always keep accuracy by prescribed recutting.
